Expected behaviour

When querying blocks with from to, if the "to" block is higher than the tip, the error below is thrown. It would be better to just return the blocks that are there in the range and not panic

Actual behaviour

{
  "errors": [
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        10,
        "number"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        10,
        "gasUsed"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        10,
        "gasLimit"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        10,
        "miner"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        10,
        "timestamp"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        11,
        "timestamp"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        11,
        "gasUsed"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        10,
        "hash"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        13,
        "timestamp"
      ]
    },
    {
      "message": "panic occurred: runtime error: invalid memory address or nil pointer dereference",
      "path": [
        "blocks",
        11,
        "miner"
      ]
    },
...

Steps to reproduce the behaviour

Start a new network, before you reach 10 blocks run

query listBlocks() {
      blocks(from: 1, to: 10) {
        number
        transactions {
          hash
        }
        timestamp
        gasUsed
        gasLimit
        hash
        miner {
          address
        }
        parent {
          hash
        }
      }
    }

-> crash

then run the same with a lower to e.g 4 and the call works
